The party began around 6pm. Traffic was blocked at the junction of Stamford Hill and Lynmouth Road and sound systems were set up on the street.

Police said they had earlier tried to get organisers to call off the event and at 7.45pm Hackney police tweeted that the party in Malvern House “is not going ahead” and asked people not to attend the area.

Tweets in reply were dismissive of the claimed cancellation, with one person replying that the event looked “pretty slamming when I went past a few minutes back”.

The block party at Malvern House, Stamford Hill N16 is not going ahead. Please do not attend the area.
